Introduction
The KY-009 “RGB” module is a handy little component that allow three color ( Red ,Green and Blue) in a single Led while having only 4 pins
- Comman cathode pin
- Anode for Red LED
- Anode for Blue LED
- Anode for Green LED
The KY-009 “RGB” module emits ‘Red’ , ‘Green’ and ‘Blue’ color but by applying different voltages on anode pins of each led we can produce different combinations of colors but in this tutorial we will only produce “Red” “Green” and “Blue” colors only
Circuit diagram
- Connect comman cathode pin of KY-009 module to ‘GND’ pin of evive
- Connect anode of Red LED to pin number 11 of evive
- Connect anode of Green LED to pin number 10 of evive
- Connect anode of Blue LED to pin number 9 of evive
Arduino code
In this code we have used three different for loops, each for loop will produce one color out of ‘Red’ , ‘Green’ and ‘Blue’ color and it will increase the intensity of light after each 100 ms
Expected result
